Hello, and welcome to the forum.
Concerning bentonite clay, the primary ingredient is hydrated aluminum silicate, others are calcium, magnesium, and iron. However, the composition can vary depending on the location in which the bentonite is found.
As far as studies done with bentonite, there are only a very few of those from which to obtain information. The main information is that you should not use bentonite clay two hours before or after medication or any other nutritional supplements. There have been no studies on long-term safety of bentonite in humans.
White Kaolin Clay is normally used in the manufacturing of cosmetics. This clay is normally used as a face mask for circulation, exfoliating and cleansing your skin. I’ve read reports of it being used as an internal detoxing agent, but other than this I have little information on it.
In order to fully understand the die-off process, read the post which is titled “Die-off Dangers” dated August 27 on the forum.
I do not recommend the website’s detox protocol, as I do not agree with the use of psyllium powder or psyllium husk. There is a much simpler detoxing protocol which can be done for one to two weeks. It’s called “Detox Protocol.” This post can be found in the “General Discussion” section of the forum.
Please do not worry about the “Leaky Gut Syndrome” at this point. Just focus on getting your detox period out of the way. If you do have leaky gut, when you start the detox period, you will be taking the first step toward healing it.
Please let us know if you have other questions or concerns.
